Check Digit Verification of cas no

The CAS Registry Mumber 18471-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18471-99:
(7*1)+(6*8)+(5*4)+(4*7)+(3*1)+(2*9)+(1*9)=133
133 % 10 = 3
So 18471-99-3 is a valid CAS Registry Number.

4-Oxoquinolines and monoamine oxidase: When tautomerism matters

Mesiti, Francesco,Maruca, Annalisa,Silva, Vera,Rocca, Roberta,Fernandes, Carlos,Remi?o, Fernando,Uriarte, Eugenio,Alcaro, Stefano,Gaspar, Alexandra,Borges, Fernanda

, (2021)

4-Oxoquinoline derivatives have been often used in drug discovery programs due to their pharmacological properties. Inspired on chromone and 4-oxoquinoline chemical structure similarity, a small series of quinoline-based compounds was obtained and screened, for the first time, toward human monoamine oxidases isoforms. The data showed the N-(3,4-dichlorophenyl)-1-methyl-4-oxo-1,4-dihydroquinoline-3-carboxamide 10 was the most potent and selective MAO-B inhibitor (IC50 = 5.30 ± 0.74 nM and SI: ≥1887). The data analysis showed that prototropic tautomerism markedly influences the biological activity. The unequivocal characterisation of the quinoline tautomers was performed to understand the attained data. To our knowledge, there have been no prior reports on the characterisation of quinolone tautomers by 2D NMR techniques, namely by 1H–15N HSQC and 1H–15N HMBC, which are proposed as expedite tools for medicinal chemistry campaigns. Computational studies on enzyme-ligand complexes, obtained after MM-GBSA calculations and molecular dynamics simulations, supported the experimental data.

Palladium-Nanoparticles-Catalyzed Oxidative Annulation of Benzamides with Alkynes for the Synthesis of Isoquinolones

Sharma, Nidhi,Saha, Rajib,Parveen, Naziya,Sekar, Govindasamy

, p. 1947 - 1958 (2017/06/09)

A novel method to synthesize isoquinolones via oxidative annulation of N-alkoxy benzamides and alkynes using binaphthyl-stabilized palladium nanoparticles (Pd-BNP) as catalyst has been developed. This methodology affords various isoquinolone derivatives in good to excellent yields with high regioselectivities in the presence of air as oxidant. N-Methoxybenzothioamide was also found to undergo oxidative annulation with alkyne successfully and provided a sulfur analogue of isoquinolones in moderate yields. The Pd-BNP catalyst was easily recovered and reused up to four times without any apparent agglomeration. (Figure presented.).
